Speaker working Drawings
You have the choice of speaker size and (possibly) two speakers (one big and one small). You could also use two large speakers but this comes at a cost (you have to pay for the additional speaker). You can also add a third speaker in your own time. This would be the SubWoofer and would be a totally different design, which you would need to research.
Sound architecture
Sound padding - this will change the sound to become higher quality. The more that you can reduce the vibration the better your speaker will sound.Â
